True...and but there are more than one ways to skin a cat, uhh carp....can't say the smaller sized barbell eyes have ever posed a problem - it helps keel hook ride up sort of clouser style and though not totally weedless, a mono weed guard could help(working on a better snagproof river fly)...
Rod wieght, matter of preference... 5 or 6 wt might suit some people and thats great, personally I'd rather err on having the extra backbone and not need it than want it and not have it (couple of times I'm glad I had it)...besides, I had some cheap 8wt laying around with out a use and it fits the bill... Haven't noticed "line slap", granted, its not finessing out some gossamar tippet with a tiny trico with a ulralite rod...but I spook more fish from careless movements than my fly hitting the water...if you lead the fish properly, its a non issue. If you cast properly, its a non issue.
Funny thing is when I blow a cast and the fly does plop, more often than not I see the fish actually move toward the general direction of my fly than away...funny how that works out.
So again, to each his own...
May you find a rise in every puddle... - WATERBORN
